Be it known that I, FRITZ FREDERICK UEHLING, a citizen. of the United States, and resident of Passaic, in the eounty of Passaic and State of and useful Improveof which the following is a specification, reference being had there in to the accompanying drawing. This invention refers to i1eans for filter cleansing a fiuid or gas. The object is to provide a simple appliance having a wide variety of applications and intended to be built in many simple designs all havihg the same general purpose and construc- A cheap and efficient gas filter is very and my improved device aims to supply this want.

Vith these and numerous other objects in view the invention may be said to consist arrangement and eombination of parts, substantially as Will be hereinafter described and then more speCifically pointed out in the claims.j

In the annexed drawing illustrating my invention: V

Figure 1 is a sectiOnal s'ide elevation of my improved filcering means, operatively supported in its frame in the wall of a gasfilled chamber wherein it has the function of filtering the gas or fluid.

Figure 2 is a detail outside view of the cylindrical filter support or frame and its detaehable head.

Figure 3 is a side elevation of the filter mechanism proper.

Figure 4: is a vertical section on the line l, 4:, of Figure 3.

Figure 5 is an proved gas filter tistage form.

Figure 6 is a sid view of an alternative form of the filter.

Figure 7 is a cross-section of the same on the line 7, 7, of Figure 6.

Similar charaotersof reference designa like parts throughout the difierent figures of the drawing.

I will first explain the construction the filter mechanism proper and then describe the means for supporting it in posi tion for use.

The preferred form of the filter is shown in Figures 3 and 4: where it is seen to consist of a pair of porous dises, or segments of built in a plural or mul- New Jersey, have 1n' bers, may be outline view of my irnl is eonducted away the other t0 produee a 1922.' Seral No. 555,516]

any suitable porous filtering materal, such for eXample, as porcelain Or pumiCe st0ne. This filcefihg mate1ial may be any refrae tory material through Which a gas Will pass and be filtered or purified. These eireular members are. arranged in opposite sides of a cirCular casing 2 which is rebated on eachside toreceive the filtering members, and the latter are held. secrely in the rebas in the casing 2, by means of a centrallydisposed boit 6 having on one end a head 6 and washer 8, and on the other end a nut 7 and washer 8, all arranged so that When the nut 7is tightened the tWofilterimg rhembrs l, 1, W lll be firmlyheld in the re-' Cessed edges of casing 2, and a space Will thus be provided Within said casing toreceive the purified gas. ofl through a pipe nipple 3 whieh'is inter nally screW- hreaded at et and which communicates With the interior ofthe casing 2 through a passage 5. A pipe 10 for carry ing the gas away is screwed into the nipple 3, as shown in Figure 1.

Obviously the filter casing, itsinterior chamber and the number of filteririg mem ehanged or altered :without altering the eharaeter of the efieet of the eom binati0n,' and one change of this kind is r1oted in Figures 6 and .,wvhere I show a single filtering dise 1 in lieu of the two dises l, 1, which single dise is bolted to a casing 24 by"a boit 23 having a head 27 and 1 washer 26 and screwmg into an inner nut or central member so that the dise 1 *will the recessed or rebated Casing 24 has a threadthe attachment of a pipe be held securely in edge of casing 24. ed nipple 25 for or conduit Which passes through the filtering material to any -desired point.

It often happens that to seeure the best results the gas should be passed through successive filcering members or layers of fil tering material; and in order to show a way of doing this I arrange a continuous mech This gas will'pass section, through which the gas anism of several filtering units one after multi-suage or multiefect filcer. Sueh a plural construction is indicated in Figure 5 where each unit consists of a casing l7 having filtering dises 18. One device has a pipe nipple 22 for the couphng of a gas conduit; both units have finges 19 bold together by rheans of b0lts 20; and one device has a cover 19 secured on frame 9, said bolts having heads 13 and nuts 14. Tlie cover 12 can be released and removed at any time by lotisening and removing bolts13, and can be securely fastened in plaoeby tighteningthe nuts 14. Cover 12 has a central screw-threaded bearing for holding pipe 10, whicli pipe runs through frame 9 into the gas chamber and carries at the end thereof the filtering device which 1 have just explained in detail and which it exposes to the gas With which saicl oliamber is filled. To the outside of the cover 12 is connected. a pipe union Or elbow 11 and any convenient amount of piping, conduits, or passages that receive the filtered' gas from pipe 10 and carry it to any desired point in any preferred way.

Th e mode of use is apparent. By expos ing the filter t0 a gas to be filtered, so that the porous dises 1 may be in contact with the gas, the latter Will pass through them and its filtration be effected With case and success. Also I find.that loy supporting the filter proper in the manner described in a horizontal barrel or cylinder, as 9, large enough.in diameter to allow the introduction of the. filter through it or its withdrawal through it, I am enabled to s0 looate the filter in the midst of a volume of gas that it Will function in the desired manner. As to exact deta1ls, I am not to be restr1cted thereto, as many may be clianged' and vamed Within the purview or the claims, in order 1. The combination with filter, of an openended cylinder for carrying tlie saine, said cylinder being supported' in a gas chamber in a horizontal position, a removable cover :tor said cylinder, and a tubular member secured to the cover and also to the filter, substantially as and for the purposes set 0rth.

Tlie combination With a filter, of a pipe connected thereto, a supporting rame for the pipe and filter consisting 01" a cylinder mounted in a gas chamber, and a cover for said cliambcr having a central opening in Which the aforesaid pipe is secured, together with means for claxnping the cover to the cylindrical rame.

3. The combination With a filter, of a pipe conneoted' tliereto, a supporting trame for the pipe and filter consisting of a cylinder mounted in a gas chamber, and a cover for said chamber having a central opening in which the aforesaid pipe is secured, together with means for clamping the cover to the cylindrical trame, and an external gaS-COH- veying conduit or main likewise connected With the central Ope'ning in the frame cover. In testimony whereof 1 hereunto aflix my signature.
